The King was impressed by a demonstration of “fantastic” blind football when he visited a unique college preparing students for the world of work.

Charles visited the Royal National College for the Blind (RNC) to mark its 150th anniversary and was shown the training given to those enrolled – from learning braille and business skills to massage techniques.

He watched as staff and students played football using a ball that made a noise as it rolled, with instructions shouted out to a defender to help them close down the attacker taking shots at goal.

At the end of the demonstration at the further education college in Hereford, the King said “it’s fantastic” before adding: “Hearing the ball – it’s amazing.”

In a speech marking his visit and a plaque-unveiling ceremony, Charles said: “But can I just say that in everything I have been shown today, it’s been clear to me that the college is fully committed to the values represented in this motto: education, employment, empowerment.”

He added: “And I think all this has been very apparent in the impressive personal confidence and skills demonstrated by the students, particularly the ones I’ve met, and it is hugely encouraging to see how the ethos of the college provides a real preparation for life.”

During his visit, Charles spoke to students learning Braille from a decades-old machine and also saw a modern version which created the raised dot patterns of the tactile reading and writing system on the machine itself.

At one point, the monarch spotted Billy the guide dog lying under a table as its owner, Orla Rafferty, explained the special equipment she uses in maths.
